Hyaluronic Acid

Also known as HA, sodium hyaluronate, hyaluronan

What is hyaluronic acid?

Hyaluronic acid is a sugar molecule your skin makes to hold water. It can hold many times its own weight in water, which is why it plumps skin and softens fine lines caused by dehydration. It is light, it suits every skin type, and it layers with every other ingredient.
